Basic Problem
When I attempt to unmount the internal HD I get an error message saying that the disk can’t be unmounted because KM is using it. Why does this occur and how do I stop it?
Details
I’m attempting to run my iMac from an external SSD.
As part of that process I want to unmount the internal drive so that it doesn’t consume resources ( I notice that I can hear the internal drive working even though I’m booted from the external SSD).
Using Disk Utility to unmount the internal HD fails as noted above.
So I’m wondering why KM would be in use on the internal HD when that isn’t the boot drive ? Does KM have some monitoring facility whereby it is constantly monitoring the system, rather in the same way that Hazel monitors folders?
I’d appreciate any thoughts on why KM is still active on the internal drive and how to shut it down so that I can unmount the disk.
Thanks.
